I think the above question asked in GATE 2018 (physics) is wrong.
Any vector has two components. The component perpendicular to the parity axis has even parity and the parallel component to the axis has odd parity.
The opposite is true for axial vectors.
E, A vectors.
B, L axial vectors.
The correct answer per gate exam body is E, A. Why not B and L? It’s an arbitrary situation and perpendicular components of these fields will have odd parity.
